Not bad for a programmer curious to know how to integrate Java applets with web pages. However, be warned: this book is written for Java 1.5 (the famous "Tiger" version) and is therefore out of date for contemporary Java programming.
The fact that you have to type in all of the applets is actually no bad thing. Given that this is a book aimed at Java beginners, forcing you to type in the code is a good way of getting you used to the syntax. My only gripe is that Owen Bishop likes stacking up his closing braces all on one line which is a formatting no-no for me! Indentation is king.
